SPECIFICATION forming part of Letters Patent No. 634,831, dated October lO, 1899.

Application llefl October 6, 1898. Serial No. 692,829. (No model.)

To LZZ whom t may concer/t;

Beit known that I, ALBERT N. OZIAS, a citizen of the United States, residing at Racine, I

in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Price-Scales; and I do hereby declare the following to be a full, clear, and

exact description of the same, reference being had to the accompanying drawings, forming a 1o part of this specification, and to the letters of reference marked thereon.

This invention relates'to improvements in scales for indicating the value of articles at different rates per nnit, and particularly,

i5 though not exclusively, to that class of scales in which the load and the counterbalancing means for the load are applied directly to oplposite ends of a beam pivoted in iixed bearings, the object of the invention being to produce a 2o scale of simple construction not liable to get out of order and in which the ate per unit may be varied with great facility.'

To these ends the invention consists, primarily, in a scale embodying in its construe tion a beam with means supported by the beam for varying the point of attachment of the load or the counterbalanee for the load with relation to the pivotal center of the beam, which means while located entirely on 3o one side or the other of said pivotal center is counterbalanced in itself to overcome any tendency of the load-supporting devices or the counterbalaneing supporting devices to throw the beam out of balance by reason of any difference in leverage exerted thereby.

The invention further consists in certain novel details of construction and combinations and arrangements of parts, all as will be now described, and the particular features 4o of novelty pointed out in the appended claims.

Referring to the accompanying drawings, Figure l is a perspective view of a pricefscale embodying my present improvements. Fig. 2 is a top plan view of the same. Fig. 3 is a .1,5 vertical section on the line n; Fig. 2. Fig.

a is a perspective view showing an adaptation of the invention to counter-scales. Fig. is a perspective view showing adaptations of the invention wherein the variation in the 5o rate is secured by varying the leverage exerted by the counterbalancers.

Like letters of reference in the several lignres indicate the same parts.

For the purposes of the present application I have shown my present invention as adapted for use in connection with the simplest form of scales-that is to say, scales in which a single lever is mounted in iixed hearings with means for applying` the 4load of the goods to be weighed at one side of the fulcrum and for 6o applying the counterbalance for counterbalancing the goods to be weighed on the other side of the fulcrum--and referring particularly to Fig. l it will be seen that the scale illustrated therein, as well as in Figs. 3, 3, and is a scale of the suspended pan or overhead type employing a standard A, springing from a base B and having bearings A at the top in which a beam C is pivotally mounted in any usual or preferred manner. In Figs. 7o I, 2, and 3 the right-hand end of the beam is adapted for the application of the counterpoising` means, which in the form shown consist, first, of a couni'erpoise D, sliding on a graduated supplemental beam d, and a pan or plate E, suspended from the end of the beam and adapted to receive supplemental weights bearing graduations of value in accordance with the well known system of moneyweight`7 scales. The supplemental beam d 8o is properlygraduated and bears indications of value thereon in the scale shown in denominations of one cent, running from O to 10, meaning from nothing to ten cents. The opposite or left-hand end of the beam in these iigures is shown as of a somewhat triangular shape in top elevation, the front bar F being preferably segmental or curved in the are of a circle struck `from the angle formed by the union of the two back barsfandjf. At this 9o angle I preferably form a pivotal bearing g] for the reception of a counterbalanced loadlever G, which is adapted to swing horizontally and is provided at its forward end with an indicator or edge adapted to register with rate-graduations which are marked on the segment F. The pan II or equivalent loadreferred to.

ver G, together with the pan, is always applied at the same point upon the beam with reference to the pivotal center of the beam, and consequently said load-lever when putin balance with itself may be swung to any point of adjustment without in any wise afiecting the balance of the beam; but it is obvious that any additional load applied to the end of the load-lever will affect the beam in a direct ratio to the adjustment of the lever with respect to the pivotal center of the beam, and hence by varying the leverage exerted by the load a rate-scale may be established with uniform value or costcounterbalances adapted to be applied to the opposite arm of the beam.

In the preferred construction the forward end of the counterlmlanced load lever is adapted to contact with the upper surface of the segment when an additional load is applied thereto, and the pan H or other goodssupporling device is preferably carried on a pivotal center, such as 7L, which pivotal center, together with the pivotal center g, is preferably in substantially horizontal alinement with the scale-beam pivot and pivot for the supplemental counterpoise-support at the opposite end of the beam, the relationship with respect to the horizon between these three sets of pivots determining the sensitiveness of the scale, although the position of the pivot g is not of so much importance and may be varied considerably without producing material inaccuracy. The pivot g may be prevented from escaping, so as to detach the load-lever by a guard g', and the pivot z may be similarly held by a guard 7V, while excessive upward movement of the outward end of the load-lever G maybe prevented by a guard 7b2.

In Fig. 4, wherein an adaptation of the scale is shown to an ordinary counter-scale,

the letter II indicates a base of any suitable design, and C1 the beam pivotally mounted on said base and having an arm C1", bearing graduations of value, and a pendant C for theapplication ofsupplementalweights. rIhe left-hand end of the beam preferablyoverlies the base II and is made with its front and rear edge bars D5- preferably substantially segmental and with a central cross-bar DG. The central cross-bar DG pivotally sugports a load-carrying lever G5, to the forward end of which. is attached by a pivotal bearing g5 a eounterweight gli. The attachment bearing the counterweight QG extends upwardly above the load-lever and has rigidly attached thereto a spider for supporting a scoop or platform QT for the reception of the goods or articles to be weighed, the counterweight serving to maintain the same in its proper position eenload-lever. The opposite end of the load-1ever supports by a pivotal bearing gs a second counterweightg9, which is of sufficient weight to bring the whole load-supporting lever, with the parts connected therewith or carried thereby, into a state of balance upon pivotal connection with the beam, the relationship between the parts in this construction being similar to that secured in connection with Figs. l, 2, and 3 and permitting the loadlever to be shifted horizontally to any angle without disturbing the balance of the beam itself. For convenience in turning the loadlever on the beam I have provided a handwheel M, and the front bar D5 on the wheel may be graduated to indicate rates of value, and one edge of the load-lever may register therewith for convenience in adjusting the parts. The arm C5 of the beam carries a sliding poise c5, adapted to register with the indications of cost on the said arm, and supplemental weights bearing indications of cost may be employed on the pendant for indicating cost-prices higher than the capacity of the beam will permit.

In using either of the forms of scales so far described the load-lever is adjusted to the proper rate-indication either before or after the goods are placed in the receiver and the sliding poise is moved alongthe opposite arm of the beam to secure a balance, or if the goods are of greater weight than can be balanced by the sliding poise alone supplemental weights are added to secure a balance, and in determining the ultimate cost the values of the supplemental weights are added to the value indicated by the sliding poise, as is usual in price-scales now in com mon use. To determine what quantity is to be given for a known price a sliding-poise is moved to the desired graduation or the desired number of supplemental weights are placed in position, the load-lever is moved. to the desired rate per unit, and the goods are added to secure a balance, all as will be readily understood by those skilled in the art.

The use of a counterbalance-load lever mounted on a center and supported entirely to one side of the pivotal center of the beam, it is obvious, is not confined to a construction wherein the weight of the goods or articles to be weighed is carried by said lever; but the goods or articles may be applied. to the arm of the beam and bea-r a fixed ratio to the pivots of the beam, while the variation in the weight may be secured through the medium of a weight-lever similar to that heretofore described, but adapted to receive counterpoise weights orsupplemental weights having a definite value. In Fig. 5 I have illustrated such a construction in a simple form of scale. Referring now to this iigu re, N indicates a standard or'base having a beam o pivotally supported in its upper end and adapted to bear at one of its ends a suspended pan or goods-receiver I? for the reception trally above its pivotal connection with the of the goods or articles to he weighed. The

. opposite arm of the beam is made similar to the left-hand arm of the beam in Fig. l that is to say, with a segmental `front bar Q and rear bars Q, which at their junction are adapted to pivotally support a load-lever R.

IIO

rlhis load-lever carries near its front forward end a bearing, from which a pan or weightreceiver S is suspended, and at its rear end a counterweight T, which will place the said lever and pan S in balance on its own pivot and will permit the said lever to be swungin either direction without disturbing the balance of the beam itself. The segment-al front bar of the beam is graduated to indicate rates or unitprices and a series of segmental weightsUare provided to indicate cost-prices. In using a scale of this character the load-lever is adjusted to the desired rate on the beam. The goods are placed on the pan P and the beam brought into balance by the use of supplemental weights U, the combined value of which indicates the cost-price of the goods being weighed.

The precise location of the graduations for indicating rates is obvious and easily determined by experimentation or by mechanical calculation when the length of the arms of the beams and the weights to be handled are known, as is ordinarily done by scale makers and designers in producing a new line of scales.

The pivot for the load-lever, it will be observed, is preferably made so as to permit said lever to move in a vertical as well as in a horizontal plane, the vertical movement being, however, very slight and simply sufficient to enable it to be placed accurately in balance with itself upon its center'.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, is-
